State plans to file emergency rules for 'petcoke'

Gov. Pat Quinn announced Monday that emergency rules are being filed this week with the Illinois Secretary of State. They'll be reviewed by the Illinois Pollution Control Board and are expected to take effect before the end of the month.

The rules require storage facilities to install dust suppression systems, among other things.

They mimic standards outlined in an agreement announced last month between the city and an Indiana company that stores and handles the substance.

Last month, city and state officials reached an agreement with the company to remove petroleum coke from Chicago's Southeast Side.

"Petcoke" is a byproduct of oil refining that's been accumulating along shipping channels and has sparked health and environmental concerns.
